My record is AOTC which I saw 9 times. I would have seen ST:XI a lot more than the 5 times I went but circumstances kept making it impossible, something I regret.
(I freaking hated The Dark Knight and if I could get a refund of the hours I spent watching it I would.)
i saw all three star wars prequel movies twice. Revenge of the Sith i wish i saw more times.
